yBRUSH-CYLINDER FOR THREAD-DRESSING MACHINES.

SPECIFICATION forming part of Letters Patent No. 746,946, dated December 15, 1903.

Application filed May 18, 1903.

f To M7/Z whom, t may concern/.-

Be it known that I, GEORGE A. FREDEN- BURGH, a'citizen ofthe United States, residing at the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Brush-Cylinders for Thread-Dress ing Machines,of which the following is a speciiication.

This invention relatesto a brush-cylinder adapted for a thread-dressing machine.

The invention consists in the combination of a stationary steam-pipe mounted in proper supports on the machine-frame, a tubular shaft surrounding said steam-pipe, a rollercage secured upon each end of said tubular shaft, a cylindrical tube'surrounding said tubular shaft and divided longitudinally into halves, each half of said tube provided With bristles upon its exterior surface, means for locking the two halves of said tube to the said tubular shaft, and means for rotating said brush-cylinder, all as hereinafter described, and speciiically set forth in the claims.

In the accompanying sheet of drawings, Figure l represents a central longitudinal sectional vieW of my improved brush-cylinder for a thread-dressing machine. Fig. 2 is a longitudinal elevation view of one of the halves of the brush proper. Fig. 3 is an end elevation view of Fig. 2. Fig. 4 is a crosssectional view taken in line X X of Fig. 2. Fig. 5 is an enlarged longitudinal section of a portion of the brush-cylinder and its parts, taken in line Y Y of Fig. 1. Fig. 6 is a crosssectional view of the brush-cylinder, taken in line Z Z of Fig. l. Fig. 7 is a front elevation of the roller-cage, and Fig. 8 is a side elevation of the same.

` Like letters indicate like parts.

A A represents a portion of the machineframe, upon which brackets or supports B B have each' a box d, provided with a cap e, which is secured to each box by bolts f f, that enter threaded openings f f', as seen in Fig. 5. A steam-pipe g is mounted in the boxes d, and a'set-screw h, which enters through the caps e of the said boxes, serves to hold the said pipe in a iixed position in the manner shown' in Fig. 5. A tubular shaft/L- loosely surrounds the steampipe g sensi No. 157,721. (No man.)

between the brackets or supports B B and has each end circumferentially screw-threaded.

jj are two circular sleeves, each of which has a portion 'of its interior surface screwthreaded to receive the threaded ends of the tubular shaft t', and each of said sleeves is firmly securedto said shaft by dowel-pins, as indicated at k la in Fig. 5. i Y C is the brush-cylinder proper, comprisin aA hollow wooden tube which is divided longitudinally throughout its length into halves ZZ, and each half of said brush is provided with bristles m m, secured upon its exterior surface in any suitable manner. Each of the wood halves ZZ of the cylinder O has a. series of semicircular metallic flanged strips n n, which are located in alinement with each other and are rigidly secured to the said halves Z Z by bolts o o, as shown in Figs. 1, 2, and 4.

n n' are a series of rings made fast upon the shaft i, and each of these rings has an outer lateral annular ange arranged to t over the inner lateral flange of each of the strips fn, n, and thus forming a means for uniting or locking the halves of the brush C together, and in order to have the brushhalves Z l turn with the shaft t the keys k k' (shown'in dotted lines in Fig.`5) project a sufficient length beyond each series of rings n to enter a groove n2, (see Fig. 2,) formed in each of the iiaugod strips n of the brushhalves.

Circular disksp p are mounted upon the shaft '11, and each disk has a laterallyprojecting annular flange p to close over the ends of the halves il when-locked together as described. The ends of the halves Z Z are secured to the disks p p by screws which pass through .the annular flanges of the same, as seen in Fig. l.

In the space formed in the sleeves j j at each end of the shaft t is mounted a rollercage (see Figs. 7 and 8) comprising two rings q q, between which a series of rollers q q' are rotatably mounted.l This cage'when in position at each end of the cylinder is arranged to have its rollers revolve upon the surfaces of the sleeves j j and steam-pipe g, respectively. This brushfcylinder, constructed as described, is rotated upon the stationary steam-pipe g by means of a spur-gear r,which IOO is keyed to one of the sleevesj, and said gear lr meshes with another gear 1", which receives power from`the main or driving shaft of the machine. This brush-cylinder is adapted to lay the projecting fibers of the thread as the thread comes up from the sizing-box, (not shown,) and in order to have all the bers laid straight the cylinder must revolve at a very high rate of speed, so that by having. the brush portion of the cylinder ymade in halves and locked together, as described, the high speed required-can be maintaiined without the danger of breakage, as happens occasioually in the use of wood strips or lagging in the construction of the ordinary brushcylinder. Furthermore, by having my improved brush-cylinder provided with suitable rollers the friction caused by the speed of rotation is much lessened.

This invention is an improvement upon the thread-dressing machine shown and described in Letters Patent of the United States No. 702,786, issued to me June 17, 1902.

I claim as a novel and useful invention and desire to secure by Letters Patent- 1. In a thread-dressing machine having two brackets or supports fixed to the frame thereof, said supports having bearing-boxes, and a steam-pipe fixed in the boxes of said supports, the combination therewith, of a brushcylinder, comprising a tubular shaft loosely surrounding the said steam-pipe and having a series of flanged rings rigidly secured upon its exterior surface, a roller-cage mounted on each end of said shaft, a Wooden tube divided longitudinally into halves, each half of said tube provided with bristles secured in its peripheral surface, a series of sernieircular flanged strips rigidly secured upon the interior surface of each of the halves of said tube and arranged to engage by their flanges with the anges of said rings in holding the two halves of said' tube together upon said shaft, substantially as set forth.

2. In a thread-.dressing machine having a stationary pipe mounted in supports of the machine-frame, the combination, of a brushcylinder, comprising a tubular shaft loosely surrounding the said pipe, a roller-cage properly mounted upon each end of said shaft, a

wood tube divided longitudinally into halves and provided with bristles secured upon the peripheral surface thereof, means for locking the halves of said tube to said shaft, and a gear rigid upon said shaft and arranged to receive power to rotate said' brush-cylinder, substantially as set forth.

In testimony whereof I affix my signature in the presence of two witnesses.
